A mud-volcano eruption occurred in Pingtung County, Taiwan, on November 12, 2025, producing five vents that expelled mud and flames up to 2 m (6.5 feet) high. Village authorities created diversion channels to prevent mud from entering nearby farmland.
A shallow M5.3 earthquake struck near Paphos, Cyprus, at 16:23 LT (14:23 UTC) on November 12, 2025, producing a rare rapid aftershock cluster. More than 20 aftershocks were recorded within the first hours, including M3.9 and M4.3 events occurring five and ten minutes after the mainshock. By the morning of November 13, the total number of aftershocks had reached 50. The Geological Survey Department reported that the early activity rate and the presence of two closely spaced events were unusual for the region’s modern instrumental record.
Effusive eruption at Nyamuragira volcano, Democratic Republic of the Congo, continues at elevated levels. Sentinel-2 imagery from November 12, 2025, shows lava overflowing the northern rim of the caldera and extending about 6.5 km (4 miles) along the northwestern flank. On November 14, 2025, TROPOMI detected a high SO2 plume at approximately 15 km (49 200 feet) altitude, confirming intensified degassing linked to sustained magma supply.
